8 Claims. (Cl. 220-111) This invention relates to improvements in a collapsible partitioned carton.

The main objects of this invention are:

First, to provide a collapsible partitioned carton which may be quickly erected and one in which the parts are securely retained in erected position merely by pressing on the opposite end edges of the collapsed carton.

Second, to provide a carton of this character which is strong and rigid when erected and well adapted as a bottle carrier or carrier for a plurality of relatively heavy articles.

Third, to provide a carton having these advantages f which may be formed of an integral blank cut and scored and then folded to collapsed position by simple steps.

Fourth, to provide a structure having a handle portion well adapted -to sustain the loads'and which when grasped acts or serves to counteract stresses tending to collapse the carton.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which:

Fig. l is a perspective View of a carton embodying the invention in erected position, a portion being broken away to disclose structural details.

Fig. 2 is a plan View of the blank in fully extended form, adhesive being conventionally illustrated as applied to certain of the areas.

Fig. 3 is a view of a partially folded blank, adhesive being conventionally illustrated as applied to certain of the areas.

Pig. 4 is a View of the completely folded blank or the carton in the knockdown, a part being broken away to show structural details.

Fig. 5 is a top view of the carton in partially erected position.

Fig. 6 is a fragmentary top view of the erected position.

Fig. 7 is a fragmentary horizontal section somewhat in perspective on a line corresponding to line 7-7 of Fig. 8.

carton in fully Fig. 8 is a vertical section on a line corresponding to line S8 of Fig. 7.

It should be understood that in the specification and claims the terms side walls'and end walls, Aor end wall members are used for convenience in designating the parts and not as limitations as the cartons may'be of any desired shape and dimensions.

The carton of the invention as illustratedis formed of an integral blank shown or extended in the liat in Fig. 2 with adhesive applied to certain areas. The carton comprises side walls 1 1 and complementary end wall members 2 2 hingedly connected to the ends of the side walls at 3, the hinging being desirably in the form of scores. The carton illustrated is provided with side walls which, in the embodiment illustrated, are of less height than the longitudinal partition to better display the contents of the carton and to provide for convenient grasping of the handle portion of the longitudinal partition. To that end CTI Patented June 28, 1955 the blank has a longitudinally extending cutout or opening between the side walls, the edges of the opening extending between the end walls and converging to provide the outwardly inclined edges 4 for the end wall members.

Pairs of longitudinal partition members 5 are hingedly connected to the swinging inner edges of the end walls at 6. The upper edges of the end longitudinal partition members are hingedly connected to each other at 7. The longitudinal partition members S have longitudinally extending slits 8 therein vertically spaced relative to their bottom edges and providing transverse partition members 9 which are hinged at l0 and provided with sealing flaps il hinged at 12. The transverse partition members are provided with tongues 13 extending from their inner edges beyond the hinges l() thereof, the tongues having notches i4 in their upper edges.

Complementary bottom members 15 and 16 are hingedly secured to the bottom edges of the side walls at 17. The bottom member 15 is provided with a sealing flap i8 hinged at i9. This sealing flap is lapped upon and secured to the outer side of the bottom member 16. The bottom member 16 is provided with an intermediate longitudinal partition member 20 which is hinged thereto at 21. The hinge 2l is in alignment With the hinge 19 when the bottom members are connected. The longitudinal partition member 20 is disposed between the pairs of end longitudinal partition members 5 and has vertical slots 22 therein through which the tongues i3 project in overlapping relation, as shown in Fig. 7, when the carton is erected. The sealing flaps of the transverse partition are adhered in properly spaced relation to the inner sides of the side walls.

The longitudinal partition members are of such length that they overlap when in erected position. The overlapping portions have handholes 23 adapted to register when the carton is in fully erected position. One of the handholes is provided with a ilap 24 hingedly connected to its upper edge at 25 and adapted to be disposed through the registering handholes as shown in Fig. l. These coacting parts provide a handle which may be conveniently grasped and one which is very strong. The flap 24 serves the purpose of preventing any substantial collapsing racking movement of the carton and displacement of the partitions in their erected properly spaced relation. This facilitates the insertion of the bottles or other objects in the compartments. The ap also serves as a grip, that is, it provides a relatively smooth surface as compared to cut edges of the hand openings as best shown i Fig. 8 and reinforces the handle.

The hinge connections '7 at the upper edges of the longitudinal partition members provide rounded smooth surfaces for grasping as is shown in Figs. l and 8. The upper portions of the longitudinal partition members are preferably adhesively secured to each other by longitudinally extending strips of adhesive 26 above and below the handholes 23 and vertical strips 27. This adds to the rigidity of the erected structure and reinforces the load carrying portions thereof and facilitates the erection.

n erecting, the overlapping ends of the iongitudinal partition members 5 automatically swing to overlapping position and as the intermediate longitudinal partition member is between the pairs of members 5, there are no projecting parts likely to engage during the erecting movement. The tongues i3 automatically swing or snap into the slots 22 in the intermediate longitudinal partition member, effectively locking or retaining the parts in erected position. As stated, it is only required that thrust be applied to the end edges of Lhe collapsed carton, as shown in Fig. 4, to swing it to the completely erected position. The grip tlap 2-'i may then be passed through the registering handholes 23 providing an elec- 3 tive handle and one which is very strong and capable of carrying heavy loads.

The carton of the invention is economical to produce as it may be formed oi a single cut and scored blank, the parts of which can be readily folded and connected by simple gluing and folding operations.

We have illustrated and described our invention in a highly practical embodiment thereof, We have not attempted to illustrate or describe other embodiments 0r adaptations as we believe the disclosure made Will enable those skilled in the art to embody or adapt the invention as may be desired.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
